Abstract

The invention provides a method for dynamic matching of a message through prejudging. The method comprises the steps that a CPU (central processing unit) receives the message and judges whether the massage is matched with a first tablebody of a connection table, if so, the massage is a keep-alive connection massage, and the first tablebody is put at the last-of-chain of the connection table. The method is used for improving the matching speed of the massage, and solves the problem of packet loss caused by excessive usage frequency of the CPU.

Description

A kind of method of message dynamically being mated by pre-judgement

Technical field

The present invention relates to computer network field, particularly a kind of method of message dynamically being mated by pre-judgement.

Background technology

Current network equipment, particularly the multicore architecture network equipment adopt the mode of connection table to E-Packet mostly, with respect to packet-by-packet handling method of message, handle processing and the forwarding speed that message can improve message greatly by stream, connect table and form a list item with the form of IP five-tuple, the IP five-tuple is former IP address, purpose IP address, protocol number, former port numbers, destination slogan, wherein the message that the IP five-tuple is identical can match in the identical list item, and message is carried out identical processing.

When the network equipment being carried out the test of stability test and maximum number of connections; tester is newly-built at least 1,000,000 connections usually; then the stream keep-alive is played in each connection; and constantly establishment connects; this moment can be because whether CPU be busy with matching message be that newly-built connection message still be keep-alive connection message, causes the too high and packet loss of CPU usage.

Based on this, prior art awaits improving really.

Summary of the invention

At the deficiencies in the prior art, the invention provides a kind of by pre-judgement to the method that message dynamically mates, make and the message time decreased of tabling look-up reduce CPU usage.

For realizing above purpose, the present invention is achieved by the following technical programs:

The invention provides a kind of by pre-judgement to the method that message dynamically mates, may further comprise the steps:

CPU receives message, and judges whether described message mates with first list item that is connected table, if coupling, then described message is that keep-alive connects message, and this list item is placed the last-of-chain of described connection table.

Preferably, described method further comprises: when described message did not match with described first list item that is connected table, then described message was newly-built connection message, sets up new list item in described connection table, and this list item is placed the last-of-chain of described connection table.

Preferably, further comprised before CPU receives message: tester carries out keep-alive to existing the connection, and creates new connection.

Preferably, described tester carries out keep-alive to existing the connection according to the order of described connection table list item, and creates new connection.

Preferably, described list item comprises the IP five-tuple, and described IP five-tuple is former IP address, purpose IP address, protocol number, former port numbers, destination slogan.

The invention provides a kind of method of message dynamically being mated by pre-judgement; be used for improving the speed of message coupling; solved in the prior art because whether CPU is busy with matching message be that newly-built connection message still be keep-alive connection message; cause the too high and problem of packet loss of CPU usage; improve the system test performance, guaranteed the safe and effective operation of network.

Description of drawings

Fig. 1 is the flow chart of one embodiment of the invention.

Embodiment

Regard to a kind of method of message dynamically being mated by pre-judgement proposed by the invention down, describe in detail in conjunction with the accompanying drawings and embodiments.

As shown in Figure 1, present embodiment provide a kind of by pre-judgement to the method that message dynamically mates, may further comprise the steps:

S1, CPU receive message, and judge whether described message mates with first list item that is connected table, if coupling, execution in step S2 then, if do not match, execution in step S3 then;

S2, described message are that keep-alive connects message, this list item are placed the last-of-chain of described connection table;

S3, described message are newly-built connection message, set up new list item in described connection table, and this list item are placed the last-of-chain of described connection table.

Preferably, further comprised step S0 before CPU receives message: tester carries out keep-alive to existing the connection, and creates new connection.

The present invention is by providing a kind of method of message dynamically being mated by pre-judgement; be used for improving the speed of message coupling; solved in the prior art because whether CPU is busy with matching message be that newly-built connection message still be keep-alive connection message; cause CPU usage too high and the problem of packet loss has guaranteed the safe and effective operation of wireless self-organization network.

Above execution mode only is used for explanation the present invention; and be not limitation of the present invention; the those of ordinary skill in relevant technologies field; under the situation that does not break away from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.

Claims

One kind by pre-judgement to the method that message dynamically mates, it is characterized in that, may further comprise the steps:

CPU receives message, and judges whether described message mates with first list item that is connected table, if coupling, then described message is that keep-alive connects message, and this list item is placed the last-of-chain of described connection table.
2. the method for claim 1, it is characterized in that, described method further comprises: when described message does not match with described first list item that is connected table, then described message is newly-built connection message, in described connection table, set up new list item, and this list item is placed the last-of-chain of described connection table.
3. method as claimed in claim 1 or 2 is characterized in that, further comprises before CPU receives message: tester carries out keep-alive to existing the connection, and creates new connection.
4. method as claimed in claim 3 is characterized in that, described tester carries out keep-alive to existing the connection according to the order of described connection table list item, and creates new connection.
5. method as claimed in claim 4 is characterized in that, described list item comprises the IP five-tuple, and described IP five-tuple is former IP address, purpose IP address, protocol number, former port numbers, destination slogan.
